Electric bikes use one car-sized lead acid battery per year. Each battery represents 30-40 percent of its lead content emitted to the environment in the production processes, resulting in about 3 kilograms of lead emitted per battery produced. When scaled up the 40 million electric bikes currently on the roads in China, this is an astonishing amount of lead emitted into the environment.
